Machine stands



United States Patent 3,107,075 MACHENE STANDS Denis Matthews, Sntton-in-Ashfield, England, assignor to Matthews 8; Ehlrhamshaw Limited Filed Mar. 13, 1961, Ser. No. 5,361 3 Claims. (Cl. 248-13) This invention is for improvements in or relating to textile linking machine stands.

These linking machine stands usually comprise a base, a steel pillar on the base, and a casting support on the steel pillar for a motor and the dial of a linking machine.

When these linking machine stands are employed for mounting linking machines for linking long pieces of fabric such as might be required for the outerwear trade the disadvantage exists that the operator has to control herself in undesirable manner in order, when in a seating position, to reach around the far sides of the linking machine.

An object of the invention is to provide means for bringing all parts of a linking machine on a stand Within easy reach of an operator from a stationary position.

The invention provides a linking machine stand, comprising a base, a support for a linking stand machine mounted on said base for rotatable displacement about a vertical axis, and a manually operable control by which desired rotatable displacements of the machine about the vertical axis are obtainable at will of the operator. Conveniently the machine is on a central vertical axis and overhung in radial manner from a pillar support, and the pillar is conversely mounted on a radial arm which is pivotally mounted on said base on an axis in vertical axial alignment with the central vertical axis of the machine, and carries a foot rest for displacement of these parts about said axis.

Freedom of rotation is enhanced by the radial arm being mounted on ball bearing races about the vertical axis.

Conveniently there are two vertically spaced ball hearing races, said base and a bracket which is secured thereon providing spaced supports below and above the ball bearing races for a pivot bolt. The ball bearing races conveniently provide inner races associated with the pivot bolt and outer races associated with the base radial arm.

The foot rest conveniently consists of a foot-engageable disc secured on the base radial arm co-axial with the vertical axis.

The linking machine dial is mounted on a support casting on said pillar and the support casting also supports a driving motor.

The above and other features of the invention set out in the appended claims are incorporated in the construction which will now be described as a specific embodiment with reference to the accompanying drawings in which:

FIGURE 1 is a somewhat diagrammatic side view of a linking machine stand according to the invention.

FIGURE 2 is a somewhat diagrammatic plan view partly n section, of the machine stand.

FIGURE 3 is an enlarged sectional view of ball bearing support means for the machine stand.

Referring now to FIGURE 1, a linking machine stand is provided of the type comprising a base 1, a steel pillar 2, and a casting support 3 on the steel pillar 2 for a motor 4 and the dial 5 of a linking machine.

The dial is overhung in radial manner from the pillar 2 by a radial arm 6 which is mounted on said casting support 3 for the driving motor 4.

According to the invention the casting support 3 with motor 4, and the pillar 2, are mounted for rotational displacer eat on the base 1 about a vertical axis A in alignment with the axis A1 of the dial 5, and a foot operable control is provided by which rotatable displacements of the machine may be obtained about the common axis A, A1 at will of the operator.

More specifically the pillar 2 is mounted on a base radial arm '7 (see also FIGURE 2) which is pivotally mounted on a pivot 8 on said base 1 in vertical axial alignment with the central axis A1 of the dial 5.

The foot operable control is conveniently a foot engageable disc 9 which is secured at '10 to the base radial arm 7 co-axial on its pivot 8.

The arrangement as thus particularly described is such that an operator, seated in a position on the front of the machine with the pillar at the rear can, by placing her foot on the foot control disc '9 and by turning this disc 9 by her feet to required extent in opposite directions, displace the linking dial 5 rotationally in either direction so as to bring any part of the dial 5 to a front position near the operator as required.

In order to provide adequate support and freedom of movement of the pillar 2 and its associated parts, ball bearing races are conveniently associated between the base radial arm 7 and the pivot 8.

More specifically as shown in FIGURE 3 the base 1 has a bush portion 11 to receive the lower end of the pivot bolt 8 and engaging on this bush 11 there is an inner race 12a of a lower ball bearing race 12. Similarly there is a sleeve 13 on this inner race 12a and engaging on this sleeve 13 there is an inner race 14a of an upper ball bearing race 14. The base radial arm 7 has a bush portion 7a which is associated with the outer races 12b, 14b of the respective ball bearing races 12, 14 and the parts are secured by a screw nut 15 screwing down the pivot bolt 8 onto the inner race 14a of the upper ball bearing race 14.

Conveniently an upper support for the pivot bolt 8 is provided by an overhanging bracket 16 (see also PIG- URE 2) secured on the base 1, conveniently with upper securing nut .17 for the pivot bolt 8 and washer 18. Conveniently also the foot operated disc "9 has a central circular opening 19 to be clear of the securing nut 17 and washer 18.

What I claim is:

l. A linking machine stand of the type described ineluding a pillar having an upper radial arm carrying a linking machine dial on an upper part of a vertical axis with freedom for work beneath the dial, having in combination a lower radial arm on the pillar incorporating a ball bearing race on a lower part of said vertical axis, a support base under said lower radial arm, a pivot secured to said base and projecting up through said ball race, a bracket secured on said base and supporting the pivot over said lower radial arm, and a foot-engageable disc secured to said lower radial arm in a manner to be coaxial with said pivot for angularly displacing the linking machine dial, while maintaining the freedom for work beneath it, said disc is angularly displaced by the foot to carry the pillar and its radial arms around said vertical axis. i

2. A stand as claimed in claim 1, wherein the pivot is a screw bolt projecting up from said base, the lower radial arm is fitted by the ball bearing race on the pivot bolt, the bracket is secured to the base in position to support the pivot bolt over the ball race, and the footengageable disc is positioned over the bracket and is secured by a peripheral part to the lower radial arm.

3. A linking stand comprising in combination a base and a pillar, a support on the pillar for a motor and for a linking machine dial, an upper radial arm mounted on said support and by which the linking machine dial is overhung from the pillar, a base-radial-arm on which 3 the pillar is mounted, a pivot on said base in axial alignment with the axis of said dial and on which said baseradial-arm is mounted, a foot-engageable disc secured to said base-radial-arm coaxially with said pivot, said pivot comprising a bolt having a lower end received in said 5 base, a ball bearing race having upper and lower inner and outer races on said pivot, a sleeve on the lower inner race, the upper inner race engaging on said sleeve, a bush portion on said base-radial-arm associated with the upper and lower outer races, an upper support bracket for the 10 pivot bolt and secured on said base, and an upper screw fastening for the pivot bolt over said bracket.
